HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (7.9 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★Oct 12, 2023
Terrible app

Barely any information and very difficult and confusing to work

★★★★★Aug 4, 2022
No content

Demonstrates how to gain your opponent’s confidence without giving them anything useful. Clever but useless.
